Abstract

(57) [Abstract] [Purpose] To provide a prepaid card which has a high anti-counterfeiting effect and which can easily and surely identify that the prepaid card is genuine. A reflection surface having a unique reflection direction characteristic, and a printing section encoding the reflection characteristic are provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card.

[0002]

[Prior art]

 In order to prevent counterfeiting of a card, methods such as providing a bar code or a magnetic bar code on the surface of the card or punching a recording surface have been conventionally used.

[0003]

[Problems to be solved by the device]

 In each of the above methods, there is a problem that the counterfeiting party can analyze the structure relatively easily, and the card can be forged by using a relatively inexpensive device.

[0004]

[Means for Solving the Problems]

 The present invention is characterized in that it has a reflecting surface having a characteristic of a reflection direction and a printing unit that codes the reflection characteristic.

[0005]

[Action]

 Light is applied from a plurality of specific directions to a reflecting surface that has unique reflection direction characteristics to reflect the light, and the reflection direction characteristics are coded and printed on the same prepaid card. The authenticity can be easily determined by comparing the printed code with.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a side sectional view. The prepaid card 1 has a plurality of fine V-shaped grooves or U-shaped grooves which are parallel to each other and which are alternately arranged at an appropriate angle to form similar parallel grooves, thereby providing a reflecting surface 2 having a unique reflection characteristic. Then, the reflection direction characteristic when light is irradiated to the reflection surface in the longitudinal direction of the card and the direction orthogonal thereto is measured, coded, and printed on the reflection characteristic code printing section 3. The reflecting surface 2 may be directly provided with irregularities on the card, but in this embodiment, a small piece cut out from a thin sheet on which a reflecting surface is randomly formed in advance is pasted, and the protective film 4 is covered on the piece. There is. When using a prepaid card, the prepaid card reading / writing machine irradiates the same light as above on the reflecting surface 2 to measure its reflection characteristics, and at the same time reads the code of the reflection characteristics code printing section 3 and compares it with the actually measured reflection characteristics. To determine the authenticity of the prepaid card.

[0008]

[Effect of device]

 According to the present invention, the print code can be copied relatively easily, but it is not easy to copy or duplicate the reflecting surface. If invisible ink is used as the printing ink, it becomes more difficult to copy and tamper.

[Brief description of drawings]

FIG. 1 is a front view of a prepaid card according to an embodiment of the present invention.

FIG. 2 is a side sectional view of the prepaid card of FIG.
